Washing Fruit & Vegetables

I always wash all my fruit and vegetables even if it says on the label it’s pre-washed, especially if I’m going to eat them raw.
Most fruit and veg grow in fields covered in pesticides, and even if you buy only organic they have been handled by people in fields, warehouses and supermarkets. And it’s not enough to wash them in water alone as most of the pesticides are designed to be water-resistant.
